SLING - SingLe INtent Grinder.
Q. What style of motor should I use?A.
56 frame with base. If you use anything else, you will have to
fabricate additional support. The SLING grinder kit is designed
with this motor style in mind.

Q. Is it rigid?A.
Yes, it is still nice and rigid. It isn't quite as rigid as
the GIB, so if you are one of those grinders that can grinder 1/2" down
to 1/16" by pushing hard enough to move a semi, this probably isn't the
kit for you. Go with a GIB 2.0.
